Abstract
A sorbent composition such as for the removal of a contaminant species from a fluid stream, a method for manufacturing a sorbent composition and a method for the treatment of a flue gas stream to remove heavy metals such as mercury (Hg) therefrom. The sorbent composition includes a porous carbonaceous sorbent such as powdered activated carbon (PAC) and a solid particulate additive that functions as a flow-aid to enhance the pneumatic conveyance properties of the sorbent composition. The solid particulate additive may be a flake-like material, for example a phyllosilicate mineral or graphite.
Claims23
1-4. (canceled)
A sorbent composition comprising a particulate blend of:
- at least about 50 wt. % powdered activated carbon sorbent having a median particle size (D50) of not greater than about 20 μm;
- and
- at least about 0.1 wt. % and not greater than about 12 wt. % of a solid particulate additive selected from the group consisting of phyllosilicate minerals, graphites and mixtures thereof.
